Question

document.getElementById returns "not a function" error :(

Asked by: jchilders_98

Hi,

What appears (to me) to be a simple javascript design is generating an error. The error is "document.getElementById is not a function."  

Here's the offending code:
  var roomCell = document.getElementByID('roomCaption');
  document.roomPicture.src=roomPix[thisPic];
  roomCell.innerHTML = "my new caption";

The first line is the one that creates the error. Can anyone tell me a) why and b) how to fix it?

I want the caption of the picture to change. It (the caption) is in a table whose row looks like:
                <tr>
                    <td width='10%'><a href="javascript:chgSlide(-1)">&lt;&lt; </a></td>
               <td id='roomCaption' width='80%' align='center' ><font size="-7">Select
                        Back or Next to View Drawings</font></td>
                    <td width='10%' align='right'><a href="javascript:chgSlide(1)">&gt;&gt;</a></td>
                </tr>

Thanks.

Good lord, I spent maybe three hours trying different configurations of those three lines of code trying to get it working. Thanks a TON for the quick response.

The document.getElementById & document.getElementByID error is incredibly difficult to spot if you have not suffered it before, so do not feel bad.  (you have now been initiated :-) ) It is up there with this one, easily spotted here but put it in frontPage and see what it looks like

<script>
TotalsSum1=TotalsSuml+3
</script>

Thx for the points, :-)

x=10O0  in frontpage is very very tough to spot as well . Does any one know what font frontpage uses for the html view?

(moral of the story:- do not use frontpage, apart from possibly some thing like this  http://www.turkmenistanairlines.com )
